APPARATUS FOR IMPREGNATING AIR WITHHYDROCARBON VAPOR.

SPECIFICATION forming part of Letters Patent No. 355,594, dated January4, 1887."

Application filed March 4, 1856. Serial No 194,036: (No model.) Patentedin England September 11, 1885, No. 10,786.

I 0 aZZ whom it may concern.-

Be it known that I, GOTTLIEB DAIMLER, a citizen of IViirtemberg,residing at Gannstadt,

in the Kingdom of Wiirtemberg and Empire of Germany, have invented a newand useful paratus, and Fig. 2 a plan.

The apparatus consists of a receptacle, A, charged with petroleum, inwhich is a float, B, having a central small hole, 0, above which isformed a cavity or basin, D, into which the petroleum enters through thehole 0, so as to stand therein at the same level as outside the float.To the bottom of the basin is fixed a central tube, E, which passesfreely into the.

tube F on the cover of the vessel A, so as to slide up or down in thesame,according as the float rises or falls with any alteration of thepetroleum-level. The lower end of the tube E is perforated, so that theair drawn in through the tube will issue in finely-divided streamsthrough the perforations'into the petroleum in the basin, and thusbecomes impregnated with the vapor thereof.

\Vhen the apparatus is used in connection with a petroleum motor-engine,the tube G is connected to the inlet-port of the engine, so that duringthe suction-stroke of the latter atmospheric air is drawn in throughthepipesF and E, and after bubbling up through the petroleum andbecoming impregnated therewith, as described, it passes through thespaces H I J and pipe G into the cylinder of the engine.

The airsupply is, by preference, heated previously to its entrance intothe apparatus, either by the waste heat of the motor-engine, in themanner described in my application for a patent, No. 179,692, or by aspecial application of heat, in order to facilitate the evaporation ofthe petroleum or to make good the heat absorbed by such evaporation. Thefloat is provided with a projecting inwardly-bent rim, K,

anda shield, L, whereby the impregnated air passing up from the basin Dwill be deflected in its course, and thus be made to deposit within therim any particles of liquid hydrocarbon it may carry with it, and whichthen flow back into the basin. By this arrangement, and by effecting thecommunication be: tween the basin and the other contents of thereservoir through a very small hole, the two uniform evaporative actionis insured, no matter what the quantity of petroleum contained in thevessel A may be.

By arranging the tube E centrally in the reservoir A the immersion ofthe perforated part thereof to-an approximately constant depth will beinsured, notwithstanding that the apparatus may occasionally assumeamore or less inclined position. p

Before passing from the apparatus to the motor-engine the impregnatedair is made first to pass round a second baffle-plate, M, and throughholes N into the chamber I, so as to be effectually deprived of allliquid particles, and from I it passes through the wire-gauze 0rperforated partition 0 into the chamber J,

which is provided at top with a safety-valve,

P, so that in the event of the igniting-flame of the engine strikingback through the pipe Gr it will only extend as far as the partition 0,and any rise of pressure resulting therefrom will escape through thevalve 1?.

I amtaware that a gas-carburetor has heretofore been composed of anoil-tank having a supply-pipe and vent-opening and inlet and outletpipes for the gas, a floating carburetor having an oil-chamber suppliedby bottom pipes to the plane of displacement, and an influx-chamberleading the gas by a series of bent pipes to and into the liquid-surfaceof the oil-chamber, whence, charged with the ICO vaporized hydrocarbon,it expands into the upper part of the oil-tank through the open top ofthe oil-chamber in the float and passes off through the outlet-pipe.that in another instance an air and gas carburetor has been composed ofan oil-tank, a float therein consisting of radial chambers, a topperforated division-plate and wicks hung in said chambers, said tankhaving gas and air inlets and the float having a top flexible pipethrough which air is forced thereinto and a bottom flexible tube throughwhich the oil in the tank enters the float, so that the level of the oilin the tank and in the float is always maintained. My invention differsfrom the above in that I provide a float containing a basin open at itstop and in communication only with the main body of liquid in theoilvessel through a small hole in the bottom of the tank, so that whilethe liquid is maintained in the basin at the same level as the main bodyit is practically isolated from the same as regards heat, combined withan air-tube fixed to the float and basin and communicating with thepetroleum in the latter through perforations below the level thereof,and a tube on the cover of the oil-vessel leading to a supply of heatedair, and in which the perforated airtube freely slides. I also providein connection with the aforesaid novel features a chamber through whichthe impregnated air from the basin passes to the outlet-pipe leading toa gas-engine, said chamber containing an automaticallyoperatingsafety-valve, whereby any pressure produced within said chamber, owingto the igniting-flame of the engine striking back into the chamber, isliberated, in which novel feature, as well as in the construction of thecarburetor before explained, my invention differs from combined gasengines and carburetors as heretofore constructed.

Having thus described the nature of my invention and the best means Iknow for carrying the same into practical effect, I claim- 1. Thecombination of the vesselA, for containing the main body of petroleum,the float B, having a central small hole, 0, and the interiorpetroleum-basin, D, supplied through the said hole and open at its topinto the vessel, and the telescopic air-tubes E and F, sliding onewithin the other, the outer tube being open for connecting with a supplyof heated air, and the interior sliding tube having perforations withinthebasin below the level of the petroleum therein and having its lowerend open and in communication with the said hole for conveying thepetroleum therethrough to the basin, substantially as described.

2; The combination of the vessel A, for containing the main body ofpetroleum, the float B, having a central small hole, 0, and the interiorpetroleum-basin, D, supplied through the said hole and open at its top,the tele- I am also aware scopie air-tubes E and F, sliding one withinthe other, the outer tube for connecting with a supply of heated air,and the interior sliding tube having perforations within the basin andbelow the level of the petroleum therein, the baffle-plate L, fixedabovethe open top of the basin, and the inwardly-bent rim K, substantially asand for the purpose described.

3. The combination of the vessel A, for containing the main body ofpetroleum, the float B, having a small hole, 0, and interiorpetroleum-basin, D, open at its topinto the vessel, the telescopicair-tubes E and F, sliding one within the other, the outer tube forconneeting with a supplyof heated air and the inner sliding tubecommunicating at its lower end with the said hole and with the basinbelow the level of the petroleum therein, the chamber J, having aperforated partition, 0. and discharge-pipe G, and the safety-valve P atthe top of the chamber above the discharge pipe, substantially as andfor the purposes de scribed.

4. In apparatus for impregnating air with petroleum vapor, a float, B,having a basin, D, open at its top directly into the receptacle andcommunicating with the main body of liquid only through the small hole0, so that while the liquid is maintained in the basin at the same levelas the main body it is practi eally isolated from the same as regardsheat, said float having an air-tube, E, communit eating with thepetroleum in the basin by perforations below the level thereof andsliding freely in the tube F on the cover leading to a supply of heatedair, substantially as and for the purposes set forth.

5. In combination with the float B, basin D, and perforated air-tube E,the projecting rim K and baffle-plate L, for retaining any liquidpetroleum carried up by the air and returning the same to the basin,substantially as herein described,

6. The combination, with the petroleum-vessel A, the float B, having thepetroleum-basin D, and the perforated airconducting tube -E,communicating with the basin below the level of the petroleum therein,of the chamber J, in communication with the "essel and through which theimpregnated air passes away, and

the safety-valve P at the top of the said chamber, whereby any pressureproduced in the latter from the flame of the impregnated air passingback to the chamber is liberated, substantially as and for the purposesset forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 13th day of February, A. D.1886.
